Perfect Orthodontic Performance
• Made of stainless steel and biomedical techno polymer
• The male screw is not in contact with the acrylic resin: the function of the screw will not be influenced by the quality of the procedure and a non-compliant curing time.
• Continuous expansion movement: the high pressure injection of the polymer allows the perfect copy of the male thread of the screw thus ensuring a steady expansion transmission without the risk of undesired turning back.
• The self-centering rectangular guides ensure a biomechanical and absolutely controlled symmetrical expansion.
• Two embossed arrows indicate the direction of the opening. A white arrow provided with the plastic placement tab may be easily applied when using an acrylic color similar to the polymer body.
